Another object is to provide means, actuated by the same iluid pressure motor, for suddenly.

l greatly incrSi11S the pressure between the pressing elements as they are brought in contact with one another.

Another objectis a simple and economical lever mechanism of the general type of my application e@ ser. :10.653580, med Jan. 27. 1933, which initially applies the pqwerof an actuator to quickly Dreliminarily closethe press with a small movement `of the actuator through a comparatively small leverage and to finally close the press through a Q5 great. powerful leverage with a greater movement of the actuator, or a mechanism for transferring movable` the movement oi an actuator to the pressing element, or head, carrying lever, through a differential levermechanism automatically operable to quickly ,close the press through one leverage and to shift to' a more powerful leverage automatically to inally close the press when thepress head encounters resistance.

A further object is to provide means to maintainthe press in a closed position, after it has once been closed by the operator, without further attention from. the operator, and means to allow the press to open automatically from this position if the iluid pressure supply is temporarily 4o interrupted and means to prevent the press from closing again when the fluid pressure supplyy is again continued unless it is ciosedzin the regular manner by the operator.`

vAnother obiectoi the invention is an actuating mechanism for the movable element or head oi the ,pressing machinaconsisting .of a head carry'in lever and a second lever which are successiyeiy -movable to close the press under heavy pressure, a motor. including a cylinder carried by 5o orfthrusting lagainst one lever and a piston having its rod thrusting against the other lever wher; Y the levers move in opposite directions tsetherwith means preferably.. coactins, means on the""l eve rsthemselves for delaying the move- 55 mentoiihe second leveruntil the press is closed and then permitting movement oi the second lever to transfer its movement to the head carryhm lever to close the press under nal pressure; or in other words, an actuating mechanism, including scissor-like levers with a motor carried r5 by the levers for actuating the levers successively.

It further has for its object a oating motor between two successively actuated levers operating to close the press, whereby the force of the motor first acts with a short leverage to close the press through the head carrying lever and with a long leverage through the second lever and the head carrying lever to close the press under nal pressure or levers or other means utilizing both the action and reaction of the motor parts to preliminarily and nally close the press.

In the drawings:-

Flgure 1 is a side elevation, partly in section, in which the movable pressing element and its actuated means is shown by full lines in an extreme open position and by dotted lines in a nearly closed position.

Flgurez is a similar view, the press being closed and the parts in position to produce great pressure.

This pressing machine mechanism comprises, generally, cooperating pressing elements, that is, a buck and a head movable toward and from the buck, a head carrying lever pivoted between its ends to the trame of the machine and carrying the head on its front arm, means ioractuating the lever including a motion transmitting part and connections between said part and the :ear arm of the lever to successively apply power to said arm between its ends and at its rearend.

The motion .transmitting part isfhere shown as a iluid pressure cylinder connected by trunnion means toth'erear arm of .the head-carrying lever said cylinder having a piston rod connected to the frontarm o! a second lever, said lever being. pivoted between its ends to the frame ot the machine and having a roller pivotally mounted in itsrear arm.

The rear arm oi the second lever normally coacts with ineens to hold it from pivotal movement. and moves out oi engagement with said means when the press approaches preliminary closed position and in to-engagement with a. fulcrum on the-rearlarm of the head carrying lever to permit pivotal movement of the second lever and actuate the head carrying lever Vthrough a high, powerful leverage.'

- In said drawings, i is the base of the machine and is adapted to rest upon a table or bench and 55 upon said base is mounted the buck support. 2 and the buck 3.

Pivotally mounted at 4 on the upper end of a vertically extended projection 5 of the main base I is a head carrying lever having two arms 6 and 1 and having connected to the arm 6 the press head 8. Y

Said head and the buck 3 may be of any shape and equipped with the regular covering or nish required by the work undertaken.

Pivotally mounted on the arm 1 by means of the trunnion ring 9 and the trunnion I0 is a cylinder II in which is reciprocally mounted a piston having a downwardly extending piston rod I2 pivotally connected at its lower end by means of the pin I3 to the lever I4, Figure 2.

The lever I4 has a roller I5 pivotally mounted at I6 at the rear of said lever and the roller I5 is adapted to engage, under conditions presently described, with the surface I1 at the rear of the arm 1, Figure 1.

The roller I5 is also adapted to engage with the fulcrurn surface I8 located on the lower side of the arm 1, Figure 2.

The arm I4 is pivotally mounted at I9 on the sliding or vertically adjustable member 20 said member having a threaded rod 2| located in its lower end, Figure 2.

The rod 2I passes through the horizontal projection 22 of the base I and has a bevel gear 23 secured at its lower end, said gear 23 meshes with the bevel gear 24, Figure 2.

The bevel gear 24 is mount'ed on a rod 25 which passes through the projection 26 of the base I and through the forward end of the base I and terminates in the hand adjustment wheel 21, Figure 2.

It will now be observed that turning the hand adjustment wheel 21 transmits this motion through the rod 25 and the bevel gears 24 and 23 to the threaded rod 2| and thus causes the member 20 to raise or lower between the guides 28 and 29, Figure 2.

A retracting spring 30 is connected at its lower end at 3| to the arm I4 and at its upper end at 32 to the arm 1 and acts to yieldingly hold the arm I4 in the position as shown in Figure 1 with the stop or projection 33 of the arm I4 held against the stop 34 of the base I, and the arm 1 held against the stop pin 35 located in the projection 5 of the base I.

Pivotally mounted on the base I at 36 is a bell crank lever consisting of three arms, 31, 38 and 39. The arm 31 has a retracting spring 40 attached at the end of said arm and the other end of the retracting spring 40 is secured at 4I to the base I and acts to yieldingly hold the arm 31 against the stop pin 42 with the bell crank lever arms 38 and 39 in the position as shown in Figure 1.

The arm 38 has pivotally mounted at its lower end a pawl 43 said pawl being adapted to engage with the pin 44 located near one end of a piston rod 45. The other, or forward, end of the piston rod 45 is attached to a piston having three large diameters, 46, 41 and 48 and two smaller diameters, 49 and 50 and said piston is reciprocaliy mounted in the piston valve cylinder 5I, Figures 1 and 2.

'I'he pawl 43 has a horizontally projecting arm 52 which is adapted to engage with the roller 53 mounted on the end of the arm 54 of a bell crank lever, said lever being pivotally mounted at 55 on the base I and having an upwardly extending arm 56 to the upper end of which is attached the rod 51 said rod passing through the buck support 2 and having a knob 58 at its forward end, Figures 1 and 2.

The pawl 43 has a retracting spring 59 attached to the arm 53 of said pawl and this spring acts to yieldlngly hold the arm 52 in contact with the roller 53 at all times as shown by Figure 1 and by the full and dotted lines in Figure 2.

The roller 53 tends to keep the arm 52 in approximately a horizontal position due to the arm 56 resting against the stop pin 68 thus maintaining the engagement of the pawl 43 with the pin 44, however if the knob 58 is pushed rearwardly by the operator this motion is transmitted by the rod 51 and the bell crank arms 56 and 54 to the roller 53 and causes said roller to move downwardly thus depressing the arm 52 and raising the pawl 43 disengaging said pawl from the pin 44 as shown by the full and dotted lines in Figure 2.

'I'he piston valve rod 45 has a retracting spring 6I attached to the rear end of said rod and this spring acts to yieldingly hold the rod 45 and its attached piston as shown in Figure 1 with the piston 46 against the stop 62; therefore when the piston valve is in the position as shown in Figure 2, if the knob 58 is pushed rearwardly when the pawl 43 disengages from the pin 44 then the piston of the piston valve will assume the position as shown in Figure 1 due to the action of the spring 6I.

The arm 39 is normally held in the position as shown in Figure 1 by the action of the spring 48 and said arm is adapted to engage with the piston rod head 63 when said head moves from the position as shown in Figure 1 to that shown in Figure 2 and this engagement causes the arm 39 to swing downwardly about the pin 36; this motion of the arm 39 is transmitted through the arm 38 to the pawl 43 and causes said pawl to move from the position as shown by Figure 1 to the position shown by the full lines in Figure 2; this motion of the pawl 43 is transmitted through the pin 44 to the piston valve rod 45 and causes said rod and its attached pistons to move within the piston valve cylinder 5I from the position as shown in Figure 1 to the position shown in Figure 2.

The upper cylinder head of the cylinder II is connected by means of the conduit 64 and the T connection 65 and the conduit 66 to the iluid pressure supply valve 61; said valve is connected by the conduit 68 to a source of iiuid pressure supply and may be any ordinary type of self closing valve such as is commonly used for this purpose and is mounted on the buck support 2 and adapted to be opened by an operating handle 69.

The side outlet branch of the T connection 65 is connected by means of the conduit 10 to a port 1I located approximately in the center of the piston valve cylinder wall 5I.

There are two other ports in the cylinder wall 5I the port 12 is located to the rear of the port 1I and is connected by the conduit 13 to the same source of iiuid pressure supply that supplies the valve 61, Figures 1 and 2.

The third port 14 enters the cylinder Wall 5I in front of the port 1I and is connected'by the conduit 15 to the fluid pressure shut-oil valve 16 said valve being mounted on the base I and being adapted to be operated by the operating handle 11; the valve 16 may be of any self opening type, that is a type of valve that is heid open by spring or other means and may be closed only connected .by means o! the conduit `Il to the atmosphere, Figures l and 2. t will now be understood that the uid preslure supply valve I'I will normally remain closed at all times unless the operator depresses the operating handle il. while the iluid pressure shut-oit valve It will normally remain open at all'times unless .the operator depresses the operating handlel'I thus shutting oi! the valve` vIn order to cause the press toclose. iiuid under pressure must enter the cylinder Il, therefore it is necessary for the operator to depress both of the handles 69 and 'I1 because, with the press in the open position as shown by the full lines in Figure 1, i! the handle 69 alone is depressed then Vduid under pressure contained in the conduit il will'ilow through the valve 61 into the conduit 66, but instead of continuing through the 'r connection 65 and the conduit 64 and performing work in the cylinder II, it will be free to ilow lthrough the side outlet of the T nnection Si, through the conduit 'l0 and the port ll and into the space 'I9 which exists between the smaller piston diameter 5l and the cylinder wall QI, from said space the uid is tree to ow through the port I4 and the conduit 'l5 and the 'valve 16. which normally remains open, and then through the conduit I8 and escape t9 the atmosphere.

Therefore, in order to prevent the escape of the fluid. the operator must also depress the handle "il, thus closing the valve 16; when this lis done, the huid, having no further escape through the valve 'I6 must continue on through the 'l' connection 6B and the conduit t4 to the cylinder i I and cause the press to operate, in this manner both hands of the operator are kept occupied during the closing operation of the press and the danger of the operator having a hand caught between the pressing elements is eliminated, Figure l.

en uuid under pressure enters the cylinder il, it tends to force the piston and its attached piston rod I2 downwardly and also acts upwardly against the top cylinder head oi the cylinder II and tends to force said head and the attached cylinder li upwardly, Figure 1.

The downward force of the piston rod I2 acting through the pin I3 tends to rock the lever I4 in a clockwise direction about the pin I9, but is prevented from doing so because the roller B5 rests against the surface il on the arm l, said surface may be of any shape suitable for the purpose but is shown in this instance as a radius drawn from the center of the pin 4, and thus prevents a clockwise rotation of the lever I4, Figure 1.

However, the upward force of the uid pressure acting through the cylinder I I is transmitted through the trunnion ring 8 and the trunnion III to the arm l and causes said arm to rock in a clockwise direction about the pin 4: this motion is transmitted through the arm 6 to the press head l and continues until the press has moved from the position as shown by the full lines to that shown by the dotted lines in Figure l.

It will be observed that the force which moves the head from the position as shown by the full lines in Figure l to that shown by the dotted lines, which is a major portion of the total head travel, will he relatively small. since the power of the cylinder II acting through the trunnion I has a moment arm equal only to the distance from the center of the trunnion I0 and the center of the pin l as compared with the distance from the center of the pin 4 and the center of the presshead l, therefore the power of the cylinder II is conserved for use later on when the press head l is actually in pressing position.

As the press head B approaches the pressing position, the surface I1 moves from the position as shown by the full lines to that shown by the dotted lines in Figure 1 at which point the roller I reaches the end of said surface thus releasing the lever il and allowing the piston rod I2 to rock the lever I4 in a clockwise direction about the pin Il thus forcing the roller i5 onto the surface Il and the parts will move from the position as shown by the dotted lines in Figure 1 to that shown in Figure 2.

It will now be observed that the force acting upwardly on the arm 1 has been greatly increased due to the downward force of the piston l2 having been suddenly brought into effect and multipliedby means of the lever I4 using the pin I9 as a fulcrum point and exerting agreat upward pressure through the roller I5 andthe surface I8 to the arm 'I and this force is transmitted through the arm 6 to the press head 8 during the movement of the parts from the position as shown by the dotted lines in Figure 1 to that shown in Figure 2. a'

A variation of pressure between the pressing elements can be secured by raising or lowering the fulcrum pin I9 by turning the hand adjustment wheel 21, as previously described, located at the front of the press, Figure 2; also, by this means, various thicknesses of articles Vcan be accommodated between the pressing surfaces.

As soon as the uid pressure in the cylinder il is released, the retracting spring 30 will. rock the arm il from the position as shown in'Figure 2 to that shown in Figure 1 with the stop 33 against the stop 34 atwhich point the surface I I will be free to roll past the roller I5 from the position as shown by the dotted lines in Figure 1 to that shown by the full lines with the arm 'i resting against the stop pin 35.

When the operator has caused the press to close by depressing both of the operating handles 69 and ll and the press has reached thej position as shown in Figure 2, it will not be necessary for him to continue to hold down said handles in order to maintain the press in a closed position because as the piston rod I2 approaches the bottom of its stroke the piston rod head 63 engages with the arm 39 and, as previously explained, causes the pawl 43 to move the piston valve rod d5 and its attached piston from the position as shown in Figure 1 to that shown in Figure 2, similar to the movement of a piston valve in a steam engine. and it will now be obi served that in the position as shown in Figure 2 that one of the larger piston diameters, as 41,

has now moved to a point where it closes the port I4 which leads, through the conduit 15, to the valve 16, therefore it is no longer necessary for the operator to keep this valve closed pressure supply port l2, therefore, since this fluid pressure supply can now pass through the port Ii and the conduit 10, through the T connection 6i and the conduit 6,4 into the operating cylinder II', it is no longer necessary for the operator to keep the iiuid pressure supply valve il open any longer and theoperating handle 69 can be also released, Figure 2.

Therefore, when the-press reaches a closed po- 'sition as shown in Figure 2, it will remain in pressure to the other side of the piston in the cylinder Il, and thus cause a reciprocating action as in an ordinary steam engine, it is desired to maintain the piston in the cylinder Il at the end of its stroke and continual automatic reciprocation is not desired because in this Acase the normal power movement of the piston rod I2 is accomplished manually as it was done in the earliest days of the steam engine. i

When the operator desires to open the press from the position as shown in Figure 2, this can be accomplished by pushing the knob 58 from the position as shown by the full lines in Figure 2 to that shown by the dotted lines; this motion is transmitted, as previously described, through the rod 51 to the bell crank arms 56 and 54 and causes the roller 53 to depress the arm 52, thus raising the pawl 43, as shown by the dotted lines in Figure 2 and releasing the pin 44 which allows the retracting spring lilA to draw the piston valve rodv 45 and its attached piston rearwardly until the larger piston diameter 46 rests against the stop 62 and the piston valve has assumed the position as shown in Figure 1.

This motion of the piston valve moves the space 80, containing the fluid under pressure, away from the port 1I, thus cutting off the fluid pressure supply and brings the space 19,into a position where it connects the port 'Il directly with the port 14, thus allowing any remaining fluid under pressure that remains in the operating cylinder Il to escape through the port 14 and the normally open valve 16 to the atmosphere and thereby allowing the retracting spring to open the press, Figure 1.

When the press moves to the open position as shown bythe full lines in Figure -1, the piston rod head63 moves upwardly and disengages from the bell crank arm 39 and the retracting spring 40, acting through the arm 31, rocks the arm 38 in a clockwise direction about the pin 36, thus moving the pawl 43 rearwardly from the position as shown in Figure 2 to that shown in Figure 1 at which point said pawl can again engage with the pin 44 in whichv position it will be ready for the next closing operation of the press.

It will also be noted that if, when the press is in the fully closed position, as shown in Figure 2, the uid pressure supply should for any reason fail temporarily and allow the press to open, then the piston rod head 63 would disengage from the arm 39 and allow the pawl 43 to swing rearwardly to the position as shown in Figure 1, and the retracting spring 6| would draw the piston valve rod 45 and its attached piston to the position as also shown in Figure 1 and the space 80 would thus be moved to the rear and the port I2 would be disconnected from the port 'I l, therefore if the fluid pressure supply were again resumed, the press would not close itself, since the port 1| would have been disconnected from said uid pressure supply by the opening of the press, and said press could only be caused to close again by the operator depressing the operating handles 69 and 11 in the regular manner, in this manner il.' the operator found the press open and was not aware of the temporary discontinuance of the duid pressure he could not become injured by the sudden closing of the press due to the uid pressure being suddenly resumed.
